Passenger Access Means Docking Indicator for Cabin Crew

2022-05-02
CURRENT
AS7995
This SAE Aerospace Standard describes the system used by passenger boarding stairs (PBS) mobile passenger boarding ramps (PBS) and boarding bridges (PBB) to inform on-board cabin crew about the docking status of the PBS/PBR/PBB and whether it is positioned such that it is safe to open the aircraft door. Current practice calls for the PBS/PBR/PBB operator to knock on the aircraft door to inform the cabin crew that it is safe to open the aircraft door. New technologies being incorporated into PBS/PBR/PBB such as remote control systems and autonomous driving vehicles are entering the market. As such, new/updated controls and/or procedures are necessary to ensure continuing safe operations.

SOLID-STATE FREQUENCY CONVERTER 400 HERTZ, 3-PHASE OUTPUT

1989-09-01
HISTORICAL
ARP1940
This specification covers the requirements for solid-state frequency converters with 480 [or 380] V 3-phase, 60 [or 50] Hz input and 115/200 V, 3-phase, 400 Hz output capable of powering aircraft type loads requiring MIL-STD-704D quality power. The frequency converter shall be a self-contained unit suitable for the environment of intended use. Typical applications include dedicated use at passenger loading bridges (mounted under the bridge in telescoping bridge applications or fixed installation at base of stationary type loading bridges) with weatherproof enclosures or hangar/lab use where indoor fixed or portable units can be used.

Aircraft Ground Service Connections Locations and Type

2006-06-05
HISTORICAL
ARP4084A
The purpose of this SAE Aerospace Recommended Practice (ARP) is to standardize locations of aircraft ground service connections to accommodate the trend toward fixed systems, which use the passenger loading bridge as a vehicle for a source of utilities. It must be recognized that, in standardizing the locations of the aircraft service connections, they must continue to be served efficiently in those instances where mobile ground support equipment is used. There is an ever increasing number of fixed installations for aircraft servicing. The objectives to be met by standardizing the locations of the aircraft service connections are the following:

EFFECTS OF NO-BREAK POWER TRANSFER ON 400 HZ AUXILIARY-POWER UNITS AND GROUND-POWER UNITS

1992-02-01
CURRENT
AIR4651
This SAE Aerospace Information Report (AIR) describes the characteristics and effects of using no-break power transfer (NBPT) methods when switching between auxiliary-power unit (APU) and ground-power unit (GPU). The GPU may be: a Point-of-use solid-state frequency converter, engine-generator, or motor-generator b Central system powered by motor-generator or solid-state frequency converter

400-CYCLE GROUND POWER UNIT PROVISIONS FOR AIRCRAFT ELECTRICAL SYSTEM PROTECTION

2002-12-16
CURRENT
ARP760
This SAE Recommended Practice which defines the terms and tabulates the limits of the characteristics for various protective devices used in conjunction with 400-cycle ground power for civil aircraft is intended to assist the airlines in standardizing on 400-cycle protective systems. The limits found to be acceptable in the civil aircraft industry are presented.

Design Factors - Handicapped Passenger Boarding Devices

2002-07-16
HISTORICAL
AIR4652
This SAE Aerospace Information Report (AIR) covers handicapped passenger boarding devices used airside to transfer handicapped passengers between the terminal building and the aircraft. It provides an elevating platform to facilitate access to the aircraft; it does not cover devices for in-terminal or streetside transfers, wheelchairs for on-board aircraft or in-terminal usage, or aircraft boarding bridges. However, it should be recognized that for many handicapped passengers, a boarding chair is necessary for the lifting operation and movement to the passenger's seat inside the aircraft cabin. Such wheelchairs are widely used in larger aircraft, and the Federal Aviation Agency has developed a performance specification for a boarding chair for commuter aircraft.
